1) Click on a Directory listing for an Organization and see "Events" on their page... click, then see all events listed for that Organization.
2) To create a new Event for a listed Organization, then address details pre-populate. Far better/quicker user experience.
Events are not limited to "venues", an organization can be a Church, a local artist, as well pubs and restaurants.
This feature is very hard to find integrated on WP plug ins. Currently WPgeo has an offering similar at an affordable price point.
